SPECIFICATION forming part of-Lettelrs Patent No. 617,339, dated January 10, 1899 Application filed January 20,1898. Serial No. 667.224. (No model.)

To altwhpm it may concern:

' Be it known that I, ARTHUR T. JOHNSON, residing at Traverse City, in the county of Grand Traverse and State of. Michigan, have invented a nevnand useful Sash -Holder, of which the following is a specification.

Myinvention relates to that class of devices known as sash-holdersfand has for its object to furnish asimple, cheap, durable, and

eiftiti-ve sash-holder which by simple movements may be adjusted to lock the sash against upward movement or against downward movement or against eithenupward or downward movement or to permit the sash to be moved freely either up or iuown.

With this object in view my invention consists in a sash-holder comprising a dog or locking-lefve'rwitha circular opening through to make and use the same, I will now proceed Whi'Bh v Figural is a perspective view illustrating 'toldescribe its construction and operation, having reference to the accompanying drawings, Qforming part of. this. specification in' my invention in practical operation upon a window-sash. Fig. 2 is a view in sideeleva' tionof my inventiondetached from the sash,

' the edge of the window-frame being indicated A by a line and the-lock adjusted to prevent downward niovement of the sash; Fig. 3 is a similar view with the parts adjusted to pre vent raising of the sash; Fig; 4 is a similar viewwith the parts adjusted to lock the sash ngai'nsteithernp 92 down movement; .Fig. 5

is a-detail. perspective view of the eccentric detached. 1 Like lettersof reference indicate the same parts wherever they occur throughout the drawin'gsf Referring to the drawings'by letters, 'di'cates the window-frame, and B the sash.

0 indicates a dog or locking-leverwhich is adapted to lie pivoted to the sash in position to bring the end face in contact with the frame. This end face for the greater portion of its length is straight, as at D, and each end is curved, as at E and F. Projecting from its face are three stop-pins G, H, and I. A spring K is secured to the sash bya screw L and rests upon the outer face of the locking-lever G.

The lockin'g-lever is pivoted upon a block M,

which inturn is pivoted to the sash by means of a screw N, passing through a bore O, eccentrically located in the block,whereby the block becomes an eccentriqa handle P being pro-- ,vided on one edge thereof, which serves the double purpose of manipulating the bl )ck on its pivot and assisting in holding the lockinglever 'Ci'n position on the sash.

The construction of r my improved sash".-

holder will be readily understood from'the foregoing description and its operation may be described as follows; When the spring K is adjusted to bear under the stop-pin H, as shown in- Fig. 4, the locking-lever will be retained in a horizontal position, and while in this position-when the handle P of the eccentrio-block M- is turned to its upward position, which will bring a greater diameter of the eccentric block betweenits attaching-screw and the face-of the frame,-a flat central'portion D of-the loclgingele'ver will be brought into forcible contact-with? the-frame A and will securely lock the sashagainst movement 1 either up iorj down. =fiWithout changing the adjustment of: the-spring-Kfthehandle P of the eccentric block may be turned down, which'wfll bringthe shorterdiamete'r of the eccentric block inthe 'directionofthe face and withdraw the end of the'flocking-leverj from contact with the frame,' leaving the sash free't o be movedeither upward or downward: When, however; the spring'K'is adjusted to bear under: the lower stop-pinI, as shown in Figs. 1 and 2', and. the handle P turned to bring thelesser diameter of the eccentric block in the direction oftheframe, the contact of the locking-lever will be elevated and the lower-curved portion F brought-into contact with the frame; I "In this position the sash willbe free to bemo'ved upward or locked against'movin'g downward, 'Whemhowever,

IOU

' handle Pof the the spring K is adjusted to bear upon the top of the stop-pin G, as shown in Fig. 3, and the centric block, which movement, as before ex-" plained, will turn the greater diameter of the eccentric block toward the frame and firmly lock the flat surface D of the contact end of the locking-lever against the frame.

From the foregoing description of the construction and operation of myinvention it will be obvious that I have produced a simple, cheap, strong, durable, and effective sashholder which will fulfil all the objects of my invention, and while I have described what I consider to be the best out my invention I do not wish to be understood as-restricting myself to the'exact forms and arrangements shown, but hold that any slight changes or variations, such as might suggest themselves to the ordinary mechanic,

eccentric block moved downmeans for carrying- Having thus described my invention, what.

I claim as new, and desire to secure by Letters Patent, is

The combination with the sash, of the locking-lever having its contact end formed with a flat surface and curved upper and lower surfaces, stop-pins arranged in a vertical line on the face of the locking-lever, a spring socured to the sash and bearing upon the face of the locking-lever in position to engage either of the stop-pins, a cylindrical block upon which the locking-lever is pivoted having an eccentric bore, a screw passing through the eccentric bore of the cylindrical block and projecting over the face of the lockinglever, substantially as described.
